Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.
Lateral cephalometric radiograph, used for skull analysis Lateral cephalometric radiograph is a radiograph of the head taken with the x-ray beam perpendicular to the patient's sagittal plane. Natural head position is a standardized orientation of the head that is reproducible for each individual and is used as a means of standardization during ...
Schuller's view is a lateral radiographic view of skull principally used for viewing mastoid cells. [1] The central beam of X-rays passes from one side of the head and is at an angle of 25° caudad to the radiographic plate. This angulation prevents overlap of images of the two mastoid bones. The radiograph for each mastoid is taken separately.
It was described in 1938 by Schütz along with the lateral projection, and later recommended by Muntean and Fink in 1941. [3] For the Stenvers projection, a patient is placed facing the film, with the head flexed slightly and rotated 45 degrees away from the side being examined. [1] The X-ray beam will be angled 10 to 15 degrees caudal. [4]

Joints of the hand, X-ray Interphalangeal ligaments and phalanges. Right hand. Deep dissection. Posterior (dorsal) view. The PIP joint exhibits great lateral stability. Its transverse diameter is greater than its antero-posterior diameter and its thick collateral ligaments are tight in all positions during flexion, contrary to those in the metacarpophalangeal joint.
It is situated between the hand and forearm on the thumb side of the wrist (also called the lateral or radial side). It forms the radial border of the carpal tunnel . The scaphoid bone is the largest bone of the proximal row of wrist bones, its long axis being from above downward, lateralward, and forward.
In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a radiograph that suggests the diagnosis of either epiglottitis or intestinal ischemia.. In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
